Thanks txab, I'll give that a shot later today. I'm thinking I still have an issue with the actuator itself because I've had the battery disconnected a few times in the passed for durations of time for other reasons and have never noticed the defrost working again. This has been an issue for at least a year now, but so far I've managed to keep the windshield clear. I will like to sort this out however.... What all needs to come apart to access the actuator if needed. My truck has the full jam interior, leather, full console, etc...

Its certainly possible, although I dont leave anything on the dash unless something finally found it's way from the first owner 9 years later..

I assume you need to have the key in the on position with the fuses out? I saw a YouTube video of a guy doing something similar on a 2005 Sierra. Not sure it'll work the same on the new body...

Hi, I have a 2007 Sierra 1500 SLT and I cant seem to get the defrost to work anymore. The controls on the dash all seem to function correctly and I can select where I want to divert the air however it will only blow at my feet and a bit at my face. Temperatures, a/c and fan speeds can be changed with no issue and the dual climate controls all work as well. Just can't get the system to divert air where I select it. Went through other forums and Google searches and have had enough guys saying to turn the key on and off facing a southern direction and then get out and walk around the truck clockwise twice while tapping your head..... Crapola!!! Just looking for some good educated ideas as to what it could be, I'm sure this issue has come up in the passed. I'm assuming it has to do with the damper actuator or possibly as simple as a recalibration. Any help would be greatly appreciated. Thanks
